When Apple announced the iPhone X, your first smartphone with a screen OLED, the general reception was positive – this panel technology, after all, brings sharper contrasts and good battery savings, among other advantages. However, a concern has surrounded the (future) users of the new device: the propensity of OLED screens to burn-in, or, in good Portuguese, the marks that can be permanently engraved on the displays if they display a static image for an extended period of time.
Apple, in the iPhone X ad, said that its OLED screens and the smartphone software itself bring special technologies to reduce the incidence of the unwanted phenomenon … but was the conversation pure marketing or did Apple really try to alleviate the problem? ?
To resolve this question, the South Korean website Cetizen did a test beyond that extreme: pitted the iPhone X against two Galaxy devices from Samsung, The S7 edge it’s the Note8 (both, of course, also with OLED screens) and analyzed the behavior of the three competitors in a 510 hour marathon (more than 21 days!) displaying the same static image on their panels.
Surprisingly, the Apple competitor was the first to show signs of burn-in, with an almost imperceptible mark on the screen appearing after 17 hours. However, even more surprising was to note that this brand has not subsequently become sharper – the same level of (almost in) visibility remained the same until the end of the test, and the iPhone X hit the finish line as the best performing smartphone general.
Note8 started showing marks only after 62 hours, but the burn-in it was significantly more visible and it was getting worse as the days went by. The S7 edge did very well for a phone almost two years old: at the end of the marathon, the device had marks only slightly more noticeable than those of the iPhone X.
It is good to note that the three devices performed the tests with their screens configured for maximum brightness, with any light temperature compensation features (such as Apple’s TrueTone technology) turned off.
At the end of the day, even though the iPhone X did a little better than Samsung’s devices and gave strength to Apple’s burn-in, it is good to remember that the new smartphone from Apple is not immune to the phenomenon and, therefore, you must take the usual care to avoid it – that is, to prevent the same static image from being displayed on the screen for a long time. Here’s the tip!
